SLAM-SHELL BUCKET.

SPECIFICATION forming part of Letters Patent N 0. 747,210, dated December 15, 1903.

Application filed March 25, 1903.

To all whom it may concern.-

Be it known that we, ROBERT R. MOKEGH- NIE, a resident of Cleveland, and GURDON H. WILLIAMS, a resident of South Brooklyn, county of Cuyahoga, State of Ohio, citizens of the United States, have invented new and useful Improvements in OlamShell Buckets, of which the following is a specification, the principle of the invention being herein eX- plained and the best mode in which we have contemplated applying that principle, so as to distinguish it from other inventions.

Our invention relates to devices commonly referred to as clam-shell buckets, its object being to provide a device of said character economical of construction and operation.

Said invention consists of means hereinafter fully described, and specifically set forth in the claims.

The annexed drawings and the following description set forth in detail certain mechanism embodying the invention, such disclosed means constituting but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure I represents a side elevation of a device embodying our invention, illustrating same in position in which its scoop members are closed; and Fig. II rep resents same in a partial tran'sverse section on the plane indicated by line 2 2, Fig. I. Fig. III represents same with the scoop members in the open position in section taken upon the plane indicated by line 3 3, Fig. II; and Fig. IV represents a top plan view of said device, partly in horizontal section, on the plane indicated by line 4 4, Fig. III.

In the middle of the frame A, consisting of two side plates (1 Ct, suitably braced, is mounted a transverse bearing-rod B. Upon this red are mounted two separate rotatable members O 0, each embodying a power wheel or pulley c, a smaller pulley c, and an interme diate pinion c Mounted in suitable bearings in the frame are two shafts D D equidistant from the axis of rod B and laterally thereof. Each such shaft has secured thereto a gear-seginent E, meshing with the pinions 0 respectively, and is also provided rigidly secured thereto.

Serial No. 149,425. (No model.)

the rear ends being hung upon the arms 01 d,

secured upon the same shaft D- Two closing-cables H II have their ends secured to the two power-wheels c on opposite sides, respectively, and two opening-cables JJ have their ends secured to the pulleys 0 on opposite sides, respectively, in a manner such that when the cables J J are unwound the bucket will open and cables H H wind up on their respective power -wheels, and when cables H H are unwound the bucket will close and cables J J wind up, as will be readily understood from the above description and the drawings.

Suitable guidingpulleys A and a are mounted upon the top of the frame for prop erly guiding the opening and closing cables H H and J J.

In Fig. IV we have illustrated two shields a a properly attached to the frame for protecting the gear-segments E from injury or clogging by contact with the material, into which the bucket may be lowered. These shields preferably extend across and between the side plates on c.

Other modes of applying the principle of our invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

We therefore particularly point out and distinctly claim as our invention 1. The combination of a frame, two gearsegments mounted in said frame, two pinions engaging said segments, means for simultaneously rotating said pinions in opposite directions, and two scoop members, the ends of the latter being connected with said segments and supported from the frame respectively.

2. The combination of a frame, two gearsegments secured to shafts mounted in said D all frame, two pinions mounted on the latter engaging said segments, means for simultaneously rotating said pinionsin opposite directions, and two scoop members, one end of each of the latter being connected with one of said shafts, and the other being movably hung from said frame.

3. The combination of a frame, two shafts mounted upon the latter, two gear-segments secured to said shafts, two coaxial pinions engaging said segments and mounted on said frame,means for simultaneously rotating said pinions, arms secured to the ends of each of said shafts, and two scoop members, the one end of each of the latter being hung upon the arms secured to one shaft, and the other end being movably hung from said frame.

4. The combination of a frame, a bearingrod mounted in said frame, two rotatable members mounted upon said rod, each such member embodying a power-pulley and a pinion; two shafts mounted on said frame and provided with arms secured thereto, two segments engaging said pinions and secured to said shafts respectively, and two scoop members, the front end of each of the latter being movably hung from said frame, and the rear end of each of same being supported upon said arms.

Signed by us this 11th day of March, 1903.
